HP OpenVMS Alpha Version 8.3 and HP OpenVMS Version
The paging, swap, and dump file requirements are the minimum for a system with 64 MB of main memory. Additional memory in most cases adds to the space needed for these files, as will particular needs of your application. With careful system management it is pos- sible to use the paging file space as a temporary dump file.
For an OpenVMS Cluster system disk, paging, swap, and dump files cannot be shared between nodes, so the files must either be duplicated on the system disk or located on some other disk.
DECwindows Motif for OpenVMS Alpha Disk Space Requirements
To support full OpenVMS Alpha and full DECwindows Motif for OpenVMS Alpha, a system disk with at least 550 MB is recommended. However, a subset of the DECwindows Motif environment can be installed. The disk space required for the installation of DECwindows Motif is 159 MB. The permanent amount of space used is 145 MB. An additional 33 MB is needed to install the DECwindows X11 Display Server and associated files. (The DECwindows X11 Display Server and associated files are included in the OpenVMS Alpha operating sys- tem media.) These disk space requirements are in addi- tion to the disk space required for the OpenVMS Alpha operating system, as indicated in the OpenVMS Alpha Disk Space Requirements table.
Installation of the DECwindows Motif layered product gives customers the option of installing any or all of the following components:
•
•New Desktop — 24 MB. This is an optional com- ponent that allows use of the New Desktop environ- ment. It includes applications and application pro- gramming interfaces (APIs).
•DECwindows desktop — 11 MB. This component is also optional, but you should install either the New Desktop or the DECwindows desktop to create a us- able system. The DECwindows desktop is the user interface that was included in previous versions of DECwindows Motif and includes the DECwindows Session Manager, FileView, and the Motif Window Manager.
•Programming support — 32 MB. This section in- cludes support for the C, C++, Fortran, and Pascal programming languages. If you install a subset of languages, the amount of disk space required will be less.
•Example files — approximately 26 MB.
•Translated image support — approximately 20 MB.
DECwindows Motif for OpenVMS for for Integrity servers Disk Space Requirements
To support full OpenVMS for Integrity servers and full DECwindows Motif for OpenVMS for Integrity servers, a system disk with at least 707 MB is recommended. However, a subset of the DECwindows Motif environ- ment can be installed. The permanent amount of space used is 135 MB. These disk space requirements are in addition to the disk space required for the OpenVMS for Integrity servers operating system, as indicated in the OpenVMS for Integrity servers Disk Space Require- ments table.
Installation of the DECwindows Motif layered product gives customers the option of installing any or all of the following components:
•
•New Desktop - 35 MB. This is an optional compo- nent that allows use of the New Desktop environ- ment. It includes applications and application pro- gramming interfaces (APIs).
•DECwindows desktop - 8 MB. The DECwindows desktop is the user interface that was included in previous versions of DECwindows Motif and includes the DECwindows Session Manager, FileView, and the Motif Window Manager.
•Programming support - 8 MB. This number in- cludes support for the C, Pascal, and Fortran pro- gramming languages and for the New Desktop. If only a subset of languages is installed, the amount of disk space required will be less.
•Programming examples - 8 MB. This number in- cludes example audio files, the DECwindows desk- top, and the New Desktop. If only a subset of ex- ample files is installed, the amount of disk space re- quired will be less.
Layered Product Disk Space Requirements
In addition to the disk space used directly by HP or third- party layered products, there may be additional space used to store information from those products in Open- VMS help libraries, command tables, object libraries, and elsewhere. The amount of additional disk space required cannot be exactly predicted due to the pos- sibility of recovering unused space already existing in those library files. Unusually large modules contributed by layered products can also affect the amount of space
